"The proceedings before the trial court (Darjeeling) will be stayed," a bench comprising Chief Justice Altamas Kabir and justices F M I Kalifulla and Vikramajit Sen said.
The bench also sought response of the Centre and West Bengal Government on a plea of Bharati Tamang, wife of slain leader Madan Tamang, seeking handing over of the probe from CBI to Special Investigating Team (SIT) or the National Investigation Agency (NIA).
Senior advocate Mukul Rohatgi, appearing for Bharati, also sought shifting of the trial to a court in neighbouring Assam.
While seeking stay of the proceedings in the trial court, he said it was necessary as the case is in the stage of framing of charges.
"Trial court is in haste in framing the charges," he submitted and claimed that due to non-appearance of the CBI, trial court in its order has been recording wrong information while granting bail to the accused who have allegedly misrepresented the facts.
